Earlier I asked the net for a practical way to switch between system 6.0.x and system 7.0. Previous to S7.0 this was easily done using the "Blesser" application. It had ceased to function under S7.0. ewright@bach.convex.com (Edward V. Wright) and Scott E. Lasley <lasleyse@wam.umd.edu> were quick to provide a fix. Thanks guys. (This would appear to be a timely question as the answer has just appeared in INFO-MAC digest #114.) In brief, the creator for the system file has changed from 'ZSYS' in system 6.0.x to 'zsys' (a case change) in system 7.0. Blesser is looking for 'ZSYS' and thus does not find the new system file. You could change the creator of the new system file but that seems dangerous to me. The best suggestion was to make a special copy of Blesser specifically for blessing S7.0. Keep the original Blesser for blessing S6.0.x Use resedit to change the single occurrance of the string 'zsys' to 'ZSYS' and you are in business. The info-mac article further suggests that you put the the appropriate copy of Blesser in the appropriate system folder so that Blesser finds the correct system file right away. It works for me. Thanks again all. Matt Howard

To unbless the folder just move the System file into that new folder. To bless the folder just move it out again. That's all. Takes about as long as using blesser but works on any Mac that doesn't have a copy of blesser. And it saves having to mess with patching applications etc. Tony Cooper sramtrc@albert.dsir.govt.nz

To bless the folder just But it doesn't let you switch actual Systems. In this case, it would be worse than useless to keep around 6.0.* and 7.0 System Folders and move a version 6 or 7 System file from one to the other. And it wouldn't let you switch between (for example) English and French Systems, since some of the text is in the System file. -- /============================================================================\ | Francis Stracke | My opinions are my own.
